>Have somebody any idea how I could do something like that? <snip javascript and PHP> You're somewhat out of luck, as the chain of events in your typical HTTP transaction looks something like this... ---->[time]---------------------------------> client request received from browser | +-> PHP code executed on server | +-> text output to webserver (including javascript source) | +-> [drawing of cloud representing internet] | +-> text input to web browser on client side | +-> javascript executed by client ---->[time]---------------------------------> ...The only way to have the javascript affect the PHP, is to make a subsequent request /back/ to the server after the javascript has started executing. You can, for example, package the screen size into a GET variable appended to an image request. --------------------------------------------------------------------- michal migurski- contact info and pgp key: sf/ca http://mike.teczno.com/contact.html
